Abstract: Laboratory experiments have been performed to investigate the attenuation of waves propagating along a straight channel bounded by a pair of parallel rubblemound breakwaters. As a reasonable approximation, the spatial gradient of wave height is found to vary with the square of the height. Experimental data of the corresponding attenuation coefficient as a function of relative depth are presented for breakwater slopes of 1/1.5, 1/2, and 1/3. A simplified analysis is presented, and on the basis of this, the experimental results are reduced in order to provide a simple design procedure for the situation under consideration.
